GSN

In 1997 SYNAPSE set up communication equipment and software at Far East GSN sites in order to provide near real-time seismic data collection.

Russian Far East GSN stations are operated from the Albuquerque Seismological Laboratory in New Mexico:

The following stations were connected to Internet: YAK (Yakutsk), MA2 (Magadan), YSS (Yuzhno-Sakhalinsk) and PET (Petropavlovsk-Kamchatskiy). A year later Bilibino (BILL) GSN station was connected too. At most of places leased lines to local ISP were installed, and at MA2 several radiolinks were installed for data collection from remote sensors, and for retransmission to local ISP. Routing equipment, modems and other facilities were installed at all sites, with remote support and maintenance from SYNAPSE.

Pictures below show the examples of the summer field season with SYNAPSE's chief engineer/programmer Andrey Rasskazov at work at different sites, and sites themselves.

LISS software developed at ASL (http://www.liss.org/) was installed at two SYNAPSE servers (primary and secondary, for backup connections via two IP subspaces) for raw data collection via Internet from the Quanterra digitizers via DP at all sites. Connection to a definite remote port provides access to seismic data just coming from a corresponding seismic station. During first years automated monitoring facilities were based on SYNAPSE's computer-telephony system PhoneServer ™. A program explores data links and as soon as failure found, PhoneServer ™ generates voice/fax notification message to a definite remote node. E-mail is being generated as well, and it's being sent to SYNAPSE responsible person too (including paging notification). Since 2003 Nagios (www.nagios.org) monitoring software serves this purpose sending alert notification messages to the operator at SYNAPSE. Authorized users go to current network status.
